Part Number: INA241A Hi,
I'm using the INA241A2 current sense amp with 5mOhm sense resistor to monitor high side currents from an H-bridge driver. I was testing the circuit out with just a resistive load (~7Ohm) across J4 (pins 1+3) and a DC power supply…
Part Number: INA241A Tool/software:
Currently using INA241A1 part to perform inductor DCR based current sensing for 48in/12Vo/250KHz 4PH interleaved GaN based buck converter application. 1.2V reference is supplied with external op-amp buffer.
Seeing…
Part Number: INA241A Tool/software: Dear Support,
I'm using the INA241 Gain=20) with a shunt of 0.5mOhm to measure the triangular waveform of a bidirectional current of +-50A.
My Vref is 2.5V,and is generated by ADR4525. Vref is connected to REF1…
Part Number: INA241A Tool/software: Dear Support,
I'm using the INA241A2 (gain 20) with a shunt BVR-Z-R0005-1.0 to measure the triangular waveform of a bidirectional current of +-50A.
Mi output after the INA241A2 is a differential output where Vrif…
Part Number: INA241A Tool/software: The following datasheet is from INA241x.
The PSRR specification is provided under the condition VREF = 1 V.
If I use a different reference voltage such as 2.5 V or 3.3 V, Can I still use the same PSRR values stated…
Part Number: INA241A-Q1 Tool/software: Dear TI experts,
My customer made their schematic using 3 INA241A-Q1s. Could you review it?
They will use one 2V reference voltage from buffer IC to each REF1 pins of 3 INA241A-Q1s.
Best regards,
Chase
Part Number: INA241A Other Parts Discussed in Thread: INA241B Tool/software: Hi experts! I'm Yoyo.
My customer Delta is working on a hot swap circuit
They're using an MCU STM32G474MC to replace our INA241A
They think the circuit design could be…
Part Number: INA241A Other Parts Discussed in Thread: TPA3255 , TAS5634 , INA253 Tool/software: We would like to evaluate TPA3255 or TAS5634 to drive a DC voice coil motor, and inline current measure is selected. For TAS5634, PWM frequency is set to 500KHz…
Part Number: INA241A Tool/software: Hi expert,
Mu customer (Empower) is looking for a suitable three-phase motor current sensing solution, and the maximum current is 70A. Could you help to recommend best solution of high-side current sensing and low…
Part Number: INA241A Tool/software: Hi Team,
In datasheet, it describes that PWM rejection will hold output for 1us. I was wondering if this time is fixed. Will it be changed followed by common voltage or other factor in INA241A? Thanks!
